Description

用于拉链的自锁滑扣 Self-locking slider for a slide fastener

技术领域 FIELD

本发明涉及一种用于拉链的自锁滑扣,尤其是一种自锁滑扣,其上至少有一滑扣体冲压而成,锁爪与其相关部件紧凑地置于叉架中,从而获得流畅的装配。 The present invention relates to a self-locking slider for a slide fastener, in particular a self-locking slider, which has at least a slider body is stamped, the pawl member associated therewith disposed compactly in the yoke, to thereby obtain a smooth assembly.

现知道用于冲压滑扣体的机器,如在日本专利公开SHO31-5628中所揭示的。 Now knows the press machine slider body, as described in Japanese Patent Publication SHO31-5628 disclosed. 由冲压而成的滑扣体实例揭示于日本实用新型公开SHO56-45447和58-3727号中。 Stamped by the slider body in the example disclosed in Japanese Utility Model Publication No. 58-3727 and SHO56-45447. 揭示于这些实用新型公开中的滑扣体,除具有用于插入锁爪一端的开口外,上翼板上还有多种冲压而成的凸台与凹槽,在叉架装配于滑扣体上之前,用它们来定位锁爪并使其处于稳定状态。 The invention disclosed in Publication of the slider body, in addition to having an opening for insertion of the outer end of the pawl, the upper wing there are many stamped projections and recesses in the yoke mounted on the slider body before use them to locate and lock it in a stable state pawl. 日本实用新型公开SHO55-17846和58-3527号中同时描述了在冲压而成、或冲弯对应侧面而成的盒形叉架中安装锁爪的原理。 Japanese Utility Model Publication No. 58-3527 and SHO55-17846 also describes the principle of the pawl mounting stamped, punched or bent from the corresponding side of the box-shaped yoke.

如在上述先前技术资料中所揭示的,无论与弹簧为一体或不为一体,锁爪总是为宽度大于其所需宽度的金属片形。 As in the above prior art references disclosed, whether or not integrally with the spring as a whole, the pawl is always larger than the width of the desired metal sheet shaped width. 由于锁爪安装在上翼板的上表面且位于盒形叉架中,故只要锁爪具有足够的强度确保随拉手的运动与连接件接合和分离,最好把锁爪的尺寸最大限度地减小。 Since the locking pawl mounted on the upper surface of the wing and located in the box-shaped yoke, so long as the pawl has a sufficient strength to ensure that the movement of the handle with engaging and disengaging the connecting member, preferably the lock pawl maximum size Save small.

然而,传统的锁爪具有大的宽度,其目的是为了得到在一端分叉的锁爪,并在装配时防止锁爪从侧面倒下而获得自动装配。 However, the conventional locking pawls have a large width, which in order to get at the end of the pawl bifurcated and to prevent the pawl from the side, automatic assembling is obtained down during assembly. 另外,滑扣体上翼板的上表面具有多种凸台和凹槽,得用他们来支承锁爪分叉端部并在装配时稳定锁爪的位置。 Further, the upper surface of the upper wing of the slider body having a plurality of lands and grooves, they are starting to support the bifurcated end position of the pawl and the pawl assembly stability.

所以,要防止这些凸台和凹槽暴露于滑扣表面,就必须把它们与锁爪一起遮盖起来,这样叉架就必须具有比所需尺寸更大的宽度,其结果使滑扣的外表受到影响。 Therefore, to prevent these projections and recesses are exposed to the slider surface, they must be covered up with the pawl so that the yoke must have a width larger than the desired size, with the result that the slider by the outer influences.

此外,如果滑扣体冲压形成,外观问题尤为关键。 In addition, if the slider body stamped and formed, the appearance of the problem is particularly critical. 在冲压过程中,弯曲和冲孔不会带来任何问题,而在冲压上述凸缘和凹槽时,将会在被冲压区域引起塑性变形,故为了防止冲压过程中的任何塑性变形,就必须把滑扣体沿被冲压区域牢靠地夹紧,其结果是由夹卡所引起的夹痕将遗留于冲压区域。 During punching, bending and punching would not cause any problems, and when the punching of lugs and grooves, will result in the plastic deformation zone is punched, so in order to prevent any plastic deformation in the stamping process, it is necessary to the slider body is stamped along securely gripping region, as a result of gripper marks caused by gripping the left in the press area. 由于叉架的宽度有限这些夹痕太多而无法完全由叉架遮盖住,故部分夹痕会呈现于滑扣表面而使产品外表不美观。 Due to the limited width of the yoke of these folders marks too numerous to completely cover the fork, it is part of the clip will show marks on the surface of the slider unsightly appearance of the product.

按本发明第一方面,上述目的由用于拉链的自锁滑扣来实现,它包括:由接头连接的上、下翼板所组成的且上翼板上有一开口的滑扣体;跨过拉手的一部分安装于滑扣体上的C形锁爪;把上述锁爪弹性地压在所述上翼板上的片簧;容纳所述锁爪和片簧且可枢轴转动地支承拉手的叉架。 According to a first aspect of the present invention, the above object is achieved by the automatic lock slider for a slide fastener, comprising: on a linker, consisting of the lower wing and the upper wing of the slider body has an opening; across the handle portion is attached to the C-shaped locking pawl on the slider body; the said lock pawl elastically pressed against the upper wing plate of the leaf spring; accommodating the pawl and the leaf spring and pivotally supporting the handle fork. 在滑扣中,滑扣体由冲压的方法形成,上翼板上为光洁的表面,且没有遗留冲压所引起的任何压痕,锁爪为窄的刚性片。 In the slider, the slider body is formed by a process of stamping, the upper wing surface is smooth, without any indentations caused by the press left, a narrow pawl rigid sheet. 按本发明的第二方向,上述目的由用于拉链的自锁滑扣来实现,它包括:上、下翼板由接头相连、上翼板上有一开口的滑扣体;跨过拉手的一部分安装于滑扣体上的C形锁爪;把所述锁爪弹性地压在所述上翼板上的片簧;容纳所述锁爪和片簧且可旋转地支承所述拉手的叉架。 Second direction the present invention, the above object is achieved by the automatic lock slider for a slide fastener, comprising: upper and lower blade connected by a connector, the upper wing of the slider body has an opening; across a portion of the handle attached to the C-shaped locking pawl on the slider body; said pawl is elastically pressed against the upper wing plate of the leaf spring; accommodating the pawl and the leaf spring and rotatably supporting the handle forks . 在滑扣中,滑扣体冲压而成,叉架上有一对对置的凸台,它由叉架对应内壁凸出,在两凸台之间形成一空间并由凸台对应侧边导向锁爪,从而限制锁爪的倒下。 In the slider, the slider body is stamped, the forks have a pair of opposed projections, which corresponds to an inner wall projecting from the yoke, a space is formed between two bosses by side corresponding to the guide boss lock claws, thereby restricting the fall of the pawl. 锁爪为刚性片。 Pawl rigid sheet. 较优的是,在锁爪上边缘具有倾斜表面,以便与相应的凸台成摩擦约束;更佳的是锁爪一端固定在形成于滑扣体接头外边缘中的固定沟槽中;更优的是,叉架包括支腿部分,它固定于形成在滑扣体接头部分处的固定沟槽中。 Superior, the edge has an inclined surface on the pawl, to the corresponding bosses into frictional engagement; more preferably is fixed to one end secured to the pawl groove formed in the outer edge of the joint in the slider body; more preferably that the yoke comprises a leg portion which is fixed to the fixing groove portion formed in the slider body at the joint.

装配本发明的滑扣时,首先,拉手的环形端置于滑扣体上翼板的上表面一预定位置后,再把锁爪临时置于滑扣体上,并使其跨过拉手的环形端部。 After assembling the slider of the present invention, first, annular end of the handle is placed in a predetermined position of an upper surface of the upper blade of the slider body, the pawl then temporarily places the slider body and pull it across the annular Ends. 同时,锁爪的辅助部分插进形成在滑扣体接头处的支承沟槽中,而锁爪的棘爪部分松弛地插进上翼板开口中,在这种状态下,棘爪顶部伸进滑扣体导向槽中以便与拉链接触。 At the same time, the lock pawl is inserted into the auxiliary section formed at the joint groove in the support body of the slider, the pawl portion of the pawl is loosely inserted into the opening on the blade, in this state, the pawl extending into the top slider guide groove for contact with the body of the fastener. 当拉手和锁爪位于滑扣体上时,片簧位于叉架中并从底面由叉架侧壁伸出的凸台支承。 When the handle and the pawl is located on the slider body, the leaf spring is located in the yoke and the bottom surface of the support from the boss projecting from the yoke sidewall.

然后,装有片簧的叉架安装于拉手和锁爪位于其上的滑扣体上,叉架一端插进形成在滑扣接头外部处的垂直沟槽中以固定叉架,另一端固定于远离接头端的滑扣体上。 Then, with the leaf spring mounted on the handle yoke and the pawl located on the slider body thereon, the fork is inserted into one end of a vertical trench formed in the slider at the outer fork joint fixed to the other end is fixed to the away from the slider body joint end. 此时,尽管临时放置的锁爪呈现出某种程度的倾斜,但锁爪仍处于相对锁爪凸台之间的间隙中,并处于直立位置。 In this case, although the temporary placement of the pawl exhibits a certain degree of inclination, but the pawl is still in the gap between opposing pawl bosses in upright position and. 而锁爪上部边缘所形成的倾斜面由凸台定向,以便使位于叉架中的片簧准确且具有弹性地压于锁爪上表面。 Inclined upper edge of the pawl face is formed by the orientation of the bosses, so that the leaf spring accurately positioned in the yoke and having resiliently pressed against the upper surface of the pawl.

其次,叉架固定沟槽的开口端从两对应边扣紧并把叉架一端牢靠地固定住,叉架另一端则固定于滑扣体上,至此完成滑扣的装配。 Secondly, the open end of the yoke-securing groove from two corresponding sides of the fastening yoke and the end securely fixed, the other end of the yoke is fixed to the slider body, thus completing the slider assembly. 对于本发明的最终滑扣,尽管与传统的宽锁爪不同位于叉架中的锁爪为非常窄的刚性片形状,且很难保持其预定恣态,但形成在锁爪上部边缘上的两倾斜面仍由对置的凸台定向,故当拉手移动锁爪时,能够可靠地产生锁爪与连接件的接合与脱开。 For the end of the slider according to the present invention, although with different conventional wide pawl pawl yoke located in a very narrow rigid sheet shape, and it is difficult to maintain its predetermined Zi state, but is formed on the upper edge of the two pawl still inclined surface oriented opposite the boss, so that when the handle moves the pawl, the pawl can be reliably generated engagement with the connecting member is disengaged.

此外,一方面由于锁爪沿总长具有很小的宽度,另一方面因滑扣体上翼板在最小范围内进行冲压,实际上没有压痕遗留在上翼板外表面,且叉架具有足够遮盖冲压区域的最小尺寸。 Further, partly since the pawl has a small width along the total length, on the other hand because the upper wing of the slider body is stamped to a minimum, in fact, there is no indentation left on the outer surface of the upper wing, and the yoke has sufficient minimum size of the press cover region. 其结果使锁爪和片簧紧凑地位于叉架中成为可能。 As a result, the locking pawl and the leaf spring compactly in the yoke located becomes possible. 虽然本叉架与传统的宽叉架相比宽度小,但因滑扣体上翼板外表无压痕,故仍可获得非常美观的滑扣。 While the conventional yoke and a width smaller than the yoke width, the slider body but no blade outer indentation, it is still to obtain a very beautiful slider.

在图示实施例中,整个滑扣体10冲压成形,接头13沿其外部边缘具有一垂直支承沟槽13a,锁爪30的一端插入其中;一垂直叉架固定沟槽13b,叉架50的一端插入并固定其中。 In the illustrated embodiment, the entire slider body 10 press-molded connector 13 has a vertical support groove 13a along its outer edge, an end of the pawl 30 is inserted therein; a vertical yoke-securing groove 13b, the yoke 50 wherein one end is inserted and secured. 叉架固定沟槽13b从槽13a向外成阶梯地开口,且其宽度大于槽13a的宽度。 The yoke-securing groove 13b from slots 13a into the openings stepwise outwardly, and having a width greater than the width of the groove 13a. 两沟槽13a和13b与接头13一起冲压成形。 Two grooves 13a and 13b and the joint 13 with press forming. 槽13b两相对侧壁上有一对内伸的第一凸台13c,它们同样冲压成形。 A first inner boss 13c extending on opposite side walls grooves 13b, which are likewise press forming. 此外,上翼板11在朝向开口11a的一端有一叉架连接部分11b,它冲压成形,用卡紧的方式来固定叉架的另一端。 Further, the upper blade 11 toward the opening end 11a of the yoke has a connecting portion 11b, which press molding, with a fixed clamping manner in the other end of the yoke.

本发明显著特点之一是开口11a和叉架连接部分11b在滑扣体10的上翼板上冲压形成。 One significant feature of the present invention is connected to the opening portion 11a and the yoke 11b at the upper wing of the slider body 10 is formed by stamping. 由于开口11a由冲孔而成,故压痕只在冲压区周围产生。 Since the opening 11a formed by a punching, it is produced only in the indentation area around the press. 又因叉架连接部分11b一端敞开,故几乎没有任何成形压痕。 Because one end of the yoke connecting portion 11b is open, so that hardly any shaped indentations. 此外,因冲压区完全被叉架50遮盖,故叉架50的上翼板外表看不见任何不美观的地方。 In addition, due to the stamping area is completely covered fork 50, so the appearance of the upper blade fork 50 can not see any unsightly place.

拉手20通常为常规方法冲压而成的矩形金属片,其环形端21有一方孔,另一端具有方孔22。 Handle 20 is typically a conventional method punched rectangular metal sheet, one of its annular end 21 with a hole, the other end 22 having a square hole. 弹簧40为一片簧,为最简单的常规形状。 The spring 40 is a leaf spring, for the most simple routine shape. 如果锁爪和片簧被制成常规的单一构件结构,该构件必须具有较大的宽度。 If the pawl and the leaf spring is made to a conventional single structural member, the member must have a large width. 而在本发明中,由于锁爪30与片簧40为分开的部件,因而可将两部件结构的宽度减至最小的尺寸,从而也可使盒形叉架50的宽度显著减小。 In the present invention, since the pawl 30 and the leaf spring 40 as separate components, and thus the width of the two structural members can be minimized in size, and thus enable the width of the box-shaped yoke 50 is significantly reduced.

本发明中,锁爪30为滑扣的重要部件之一,从图1可看出,锁爪30本身无任何弹性。 In the present invention, the pawl 30 is one of the important components of the slider can be seen from Figure 1, the pawl 30 itself has no elasticity. 尤其是锁爪30为常见的C形金属片,它具有可保证所需刚度和强度的最小宽度,并冲压或压铸而成。 In particular, the pawl 30 is common C-shaped metal sheet having a minimum width can ensure the required stiffness and strength, and stamping or die casting. 锁爪30后端(图6左侧)有连接支脚32,它与滑扣体10装配并与锁爪体31厚度基本上相同。 The rear end of the pawl 30 (the left side in FIG. 6) connecting the legs 32, 10 is fitted with the slider body and that the thickness of the pawl member 31 is substantially the same. 锁爪的前端具有一横向偏离锁爪体31中心的棘爪部分33。 The front end of a pawl having pawl laterally offset from the pawl portion 33 of the central body 31. 棘爪33处于偏心位置是因为棘爪33可塞进图中没表示出的、在滑扣体10的导向槽中引导的对置的两排连接件中一排连接件的相邻件齿形部分之间的缝隙中。 Pawl 33 is in an eccentric position because pawl 33 is not shown in FIG into in two opposite rows of connecting member guide groove of the slider body 10 of the guide member adjacent a tooth row connector the gap between the portions. 这样,当拉手松开时可防止滑扣在连接件上滑动。 This prevents the slider slidable in the connecting member when the handle is released.

锁爪30的另一特点是,在锁爪体31的相对侧的各上部边缘中有一对斜面34。 Another feature of the pawl 30 is a pair of inclined surfaces 34 in the upper edge of the opposite side of the pawl body 31. 在滑扣装配过程中,这些斜面34由于在叉架50的相对的第二凸台54(下面将描述)之间导向而用来自动地保持锁爪30在直立位置。 In the slider assembly process, since the inclined surface 34 of the second yoke opposing projections 54 between the guide 50 (to be described below) and for automatically holding the pawl 30 in an upright position.

与常规结构相比,叉架50为细长盒形体51的形状,在一端具有可插入位于滑扣体10上的叉架固定沟槽13b中的第一固定支腿部分52,在另一端具有第二固定支腿部分53,它可通过扣紧形成于上翼板11的上叉架连接部分11b而固定在滑扣体10的上翼板11上。 Compared with the conventional structure, the yoke 50 in the shape of an elongated box-shaped body 51, having an insert positioned yoke-securing groove 13b slide on the fixing legs 10 of the first buckle body portion 52 at one end and having at the other end the second fixing leg portion 53, which may be formed on the blade fork portion 11b connecting frame 11 is fixed on the slider body 11 by fastening the blade 10. 第一固定支腿部分52具有插入叉架固定沟槽13b中的足够长度,且在其两相对侧边沿有一对第一切口52a,其中容纳着从叉架固定沟槽13b的两相对侧壁向内凸出的叉架固定第一凸台13c。 A first fixing leg portion 52 has a sufficient length inserted into the yoke-securing groove 13b in, and a pair of first cutouts 52a in which two opposite edge sides, wherein the two opposite side walls 13b receive from the yoke-securing groove fixing the yoke inwardly projecting first boss 13c.

此外,盒形体51两相对侧壁51a中心有一对第二切口51b,拉手20的环形连接部21穿过其中而可枢轴转动地连接,这样,拉手20可在预定的角度范围内枢轴转动。 Further, the box-shaped body 51 has two opposite side walls 51a a pair of second cutouts 51b, the connecting portion 20 of the annular handle 21 therethrough may be pivotally attached so that the handle 20 may be pivoted within a predetermined angular range . 盒形体51上还有一对相对的第二凸台54,它从第二切口51b的相对的横向对齐的边缘伸出。 The box-shaped body 51 also has a second pair of opposing projections 54, which are aligned from the opposite lateral edges of the second slit 51b extends. 按图示实施例,第二凸台54在滑扣1装配前平行于相对侧壁51a而凸出,在装配过程中在片簧40安装于盒形体51中之后,第二凸台54向内弯折,这样可简便地安装上片簧40并由相对的第二凸台54支承。 After pressing the illustrated embodiment, the second boss 54 parallel to the opposed side walls 51a and protrudes a slider assembly before, during assembly is attached to the box-shaped body 51 in the leaf spring 40, the second boss 54 inwardly folded, so that the support can be easily attached topsheet 40 by a spring opposite to the second boss 54. 当然,可将片簧40置于第二凸台54向内伸出的盒形体51中。 Of course, the leaf spring 40 may be disposed in a box shaped body 51 of the second boss 54 projecting inwardly of. 然而在自动装配中,需要在片簧40置于盒形体51中后再折弯第二凸台54。 In automatic assembling, however, the spring 40 needs to be placed in the box shaped body 51 and then bending the second sheet bosses 54. 在上述装配过程中,第二凸台54还用来帮助定位锁爪30并使其位置保持稳定。 In the assembly process, the second boss 54 is also used to help position the lock pawl 30 and its position is stable. 为此,相对的第二凸台54应位于与锁爪30上部边缘上形成的相对的倾斜面34相对应的位置。 To this end, an opposite second boss 54 to be located at a position corresponding to 34 opposite to the inclined surface formed by the upper edge 30 on the pawl.

图2表示在上述拉手20与锁爪30置于滑扣体10之上后,容纳片簧40的叉架50与滑扣体10装配的方式。 Figure 2 shows the handle 20 and the above-described pawl 30 is placed over the slider body 10, and the spring receiving plate 10 fitting manner slider body 50 of the yoke 40. 首先,拉手20的环形连接部21基本上置于滑扣体10的上翼板11上的中心,然后锁爪30跨过环形连接部21临时置于滑扣体10上,此时,锁爪30的连接脚部分32插进形成于滑扣体10的接头13中的固定沟槽13a中,而棘爪部分33松弛地插入开口11a中。 First, the handle 20 is a substantially annular connecting portion 21 at the center of the upper wing 11 of the slider body 10, the pawl 30 is then connected across the annular portion 21 temporarily places the slider body 10, at this time, the pawl connecting leg portion 30 is formed in the slider 32 is inserted into the fixing groove 13a 13 of the joint 10, the claw portion 33 is loosely inserted into the opening 11a. 此时,棘爪33的顶端伸进滑扣体10的连接件导向槽中,与图中未表示出的两排连接件接合。 At this time, the pawl tip 33 projects into the slider guide groove 10 of the connecting member fastening member, engaged with the coupling element rows are not shown in FIG. 当拉手20与锁爪30置于滑扣体10上时,片簧40置于叉架50中。 When the handle 20 and the pawl 30 is placed on the 10, the leaf spring 40 is placed in the yoke 50 the slider body. 然后,形成于叉架50的第二切口51b边缘上的相对的第二凸台54向内相互朝向对方弯折,用来从相对两边支承片簧40。 Then, the yoke is formed on the second edge 51b of the cutout 50 opposite to the second boss 54 is bent inwardly towards each other for spring 40 from opposite sides of the support sheet.

然后,图2所示的容纳片簧40的叉架50从上边装配到置有拉手20与锁爪30的滑扣体10上。 Then, receiving sheet 2 shown in FIG. 50 spring yoke 40 is fitted from the upper side opposite to the handle 20 and has a locking pawl 30 of the slider body 10. 叉架50的第一固定支腿部分52插进形成于滑扣体10的接头13中的叉架固定沟槽13b中,同时,第二固定支腿部分53的内表面与叉架连接部分11b的外表面相接触,此时,即使临时放置的锁爪30有某种程度的侧向倾斜,当锁爪30的斜面34由第二凸台54引导时,锁爪被导入相对的第二凸台54之间的间隙中而成为直立,从而使位于叉架50中的片簧40与锁爪30的上表面弹性地接触。 Fixing a first leg portion 52 is inserted into the yoke 50 formed on the slider body 10 of the joint 13 in the yoke-securing groove 13b of the while, the second fixing leg portion 53 connected to the inner surface of the yoke portion 11b contacting the outer surface of this case, even though the temporary placement of the pawl 30 have some degree of lateral inclination, when the pawl is guided by the inclined surface 3430 of the second boss 54, the pawl is introduced into the opposite second boss the gap between the upright 54 and to become, so that the leaf spring 50 is located in the yoke 40 in elastic contact with the upper surface 30 of the pawl.

然后,将接头13的叉架固定沟槽13b的开口端从相对两侧扣紧,用来固定叉架50的第一固定支腿部分52,叉架50的第二固定支腿部分53绕叉架连接部分11b向内弯曲成L形而固定于滑扣体10上。 Then, the open end 13 of the joint yoke-securing groove 13b from opposite sides of the fastener, for fixing the first fixing leg portion 52 of the yoke 50, the yoke 50 of the second leg portion 53 is fixed around the fork frame connecting portion 11b inwardly bent into an L-shape is fixed to the slider body 10. 至此,完成滑扣1的装配。 This completes the assembly of the slider 1. 扣紧期间,从叉架固定沟槽13b两相对内壁伸出的第一叉架固定凸台13c卡于第一固定支腿部分52上的各第一切口52a中,这样限制叉架50的垂直移动。 During fastening, a first yoke 13b extending from opposite inner walls of the yoke-securing groove fixing bosses 13c to the first fixed card slit 52a on each of the first leg portion 52, the yoke 50 so limited vertical movement.

对于本发明的如上所述而装配好的滑扣1,尽管如图4-6中所示的装在叉架50中的锁爪30,与通常的宽锁爪不同,具有非常窄的刚性片的形式,当拉手放开时,由于锁爪30的横向移动被相对的第二凸台54所限定,其预定的恣态可一直保持稳定,从而能够可靠地使锁爪30与两排连接件接合和脱开。 For the present invention described above, the assembled slider 1, although the apparatus shown in FIG. 4-6 pawl 30 in the yoke 50, the pawl usually different width, have a very narrow rigid sheet form, when the handle is released, due to the lateral movement of the pawl 30 is opposite to the second boss 54 is defined, which pleases predetermined stable state can be kept, thereby the pawl 30 reliably and coupling element rows engagement and disengagement.

另外,一方面由于锁爪30在其整个长度上宽度很少,另一方面由于只有滑扣体10的上翼板上的开口11a与叉架连接部分11b是由冲孔与模压形成,故上翼板11的表面实际上没有压痕,因此叉架50可具有足以遮盖开口11a和叉架连接部分11b的最小宽度。 Further, partly since the pawl 30 rarely width over its entire length, on the other hand since the opening 11a and the yoke only the upper wing of the slider body 10 of the connector portion 11b is formed with a punching die, so the virtually no blade surface indentations 11, 50 thus the yoke may have a minimum width sufficient to cover the opening 11a and connected to the yoke portion 11b. 因此,即使与传统叉架相比本发明的叉架具有较小的宽度,锁爪30和片簧40仍能紧凑的位于叉架50中,且滑扣体10的上翼板11的外表面上不会出现任何压痕,从而可制造出表面美观,外形别致的滑扣1。 Thus, even when compared to the yoke of the present invention with a conventional yoke having a small width, the pawl 30 and the leaf spring 40 is located still compact in the yoke 50, and the outer surface of the upper blade 11 of the slider body 10 on without any indentation, thereby producing a surface appearance, a slider unique appearance.

从上述中可很明显地看出,在本发明的自锁滑扣中,一方面由于盒形叉架50上有一对从相对侧壁51b向内凸出的相对的第二凸台54,另一方面由于锁爪30上部边缘具有一对与第二凸台54相对应的倾斜面34,这样,使锁爪为宽度很窄,强度很高的C形片状,在滑扣体装配时锁爪仍可保持在适当的位置,因此,闭锁机构无论动作与否,都可防止锁爪从侧向倒下,锁爪30能够可靠地与两排连接件接合和脱开。 As is apparent from the above may be, in the automatic lock slider of the invention, partly since the box-like yoke 50 has a pair of inwardly projecting from the opposite side walls 51b of the second boss 54 opposite to the other partly since the pawl 30 and the upper edge has a pair of projections 54 corresponding to the second inclined surface 34, so that the pawl is very narrow width, high intensity C-plate, the slider lock assembly body pawl may remain in place, and therefore, the operation of the locking mechanism, whether or not, can be prevented from falling laterally from the pawl, the pawl 30 can reliably engage with the coupling element rows and disengagement.

此外,一方面由于上述锁爪30宽度小,一方面由于支脚32插进并支撑于形成于滑扣体10上的接头13外侧中的垂直固定沟槽13a与叉架50的支腿部分52之间使固定沟槽13a和棘爪33之间具有足够的距离,故可加大锁爪30相对于两排连接件的接合和脱离动作,从而可借助拉手20进行滑扣1的可靠的自锁操作。 In addition, on the one hand due to the small width of the locking pawl 30, partly since the legs 32 inserted in and supported by the slider 13 of the outer joint member on the leg 10 of the vertical groove 13a and the fixed portion 52 of the yoke 50 is formed of between the grooves 13a so that between the fixed and the pawl 33 has a sufficient distance so that the pawl 30 can be increased engagement and disengagement operation of the coupling element rows relative to the handle 20 by means of which can be reliably self-locking slider 1 operating. 另外,由于滑扣体10的翼板上的所需冲压步骤降为最少,故可获得好的生产率,上翼板表面的压痕也可最大限度地避免。 Further, since the required pressing step of the wing plate of the slider body 10 is reduced to a minimum, good productivity can be obtained so that the upper wing surface indentations can be maximally avoided. 因此,由于与传统叉架相比,锁爪30和片簧40为分离构件,故叉架50可具有较小的宽度和较美观的外形。 Accordingly, as compared with the conventional fork, the pawl 30 and the leaf spring 40 as a separate member, so that the yoke 50 may have a relatively small width and aesthetic appearance. 从而使所得到的滑扣在滑扣体外表没有压痕,具有非常美观的外形。 So that the resulting slider in the slider body surface indentations do not have a very aesthetic appearance.
